comScore’s US video numbers came out today for February 2010. I took the liberty of digging up February 2009′s numbers and did a quick comparison between the two. Here are some things I found of interest when looking year over year:

• The duration of the average online video rose 23% in a year to 4.3 minutes.
• The percentage of the US population that watched an video online rose 7.6 percentage points from 75.5% to 83.1%.
• The videos viewed on YouTube grew by 124% to nearly 12B (yes that’s “B” for billions) video’s a month in the US.
• In 2009, Facebook wasn’t on the top 10 list of properties by Unique Viewers. In February it’s ranked number 7 with 36MM viewers.

One thing that hasn’t changed in the year though — for all the growth in video on the web — it’s still got a very long tail. In February of 2009 the top 10 properties by videos viewed made up 57.5% of the total videos. In February 2010 that top 10 list lost 2.3 percentage points to only 55.3%. This leaves lots of room for .tv! Great things to come in the video revolution.
